Note!
Vaillant offer room thermostat/time control
accessories which give accurate and economic
room temperature control as well as improved
comfort.
The boiler will now operate automatically to provide
central heating for the conditions selected on the
external controls.
After the boiler stops operating the pump will continue
to operate for a short period to fully disperse the heat
from the boiler.
After a power cut or every 23 hour in frost setting
/summer mode the pump will run for one minute to
prevent it from sticking. This will also occur during
normal operating if there is no demand for more than
24 hours.
4.6 Pump exercise
Note!
The boiler incorporates an anti-cycling
economiser control to prevent energy wasteful
on and off operation of the boiler for short
periods when in the central heating mode.
When turning the room thermostat to a higher
setting there may be a short delay before the
boiler operates.
